Moebius Syndrome: An Ocular Overview

Abstract

Moebius syndrome is a rare congenital neurological disorder whereby there is an underdevelopment or absence of cranial nerve VI (abducens) and cranial nerve VII (facial), leading to weakness or paralysis of facial and extraocular muscles. Abnormalities can also occur in other cranial nerves including the 3rd, 5th, 8th, 9th, 11th and 12th. This article will focus upon the ocular manifestations of Moebius syndrome.
